    • Good deal, great desktop computer...
Set: Intel Core i5 | 8 GB RAM | 1 TB HDD
I put this iMac into service February, 2018. Even though it was refurbished, it seemed to be in new condition. Everything works and it is much faster than other Macs I have (due to Quad core). The screen is bright and sharp. The Magic Mouse is great. I wish the keyboard had a ten key number pad. I've been back with Mac since 2004 after living in the PC world for almost 20 years. Neither world is perfect, but I enjoy the integration of the Apple eco-system and use it to the fullest with iPhone, iPads, and AppleTV's. The way that family works together is without parallel in the PC world. ======== Update (2 years later): Ultimately I found the internal 1TB HDD to be too slow...bootup took forever...so I took it to my local Apple certified support store and had them swap that out for a 256Gb SSD. It now boots very quickly and seems to have less problems with the OS clean-installed on that SSD. I keep all data on an external Drobo drive so that all that is on the SSD permanently is the OS...which leaves about 185Gb of temp storage space for working space. It also works well for iCloud documents which disappear from the local drive after a period of inactivity with a given document. ========== Update 2 (after 4 years) I have four Macs in operation ranging in dates from 2010 (running El Capitan) to a new M1 MacMini. I do have Big Sur running on this 2015 iMac without problems or stalling issues. Of the four, I think this iMac may be the most dependable and robust of the lot. It is really a good computer (after the SSD upgrade I mentioned above)....maybe the best Mac I've ever owned (and I'm sure I've had at least 10). This is a heqq of a value. ... show more

    • Great machine for those looking to get into Apple
Set: Intel Core i5 | 16 GB RAM | 1 TB HDD
What I like: The screen is fantastic The CPU runs Photoshop really well for my uses Runs well 4 years after it's released Runs programs very well What I disliked: The 1tb hard drive is slow... very slow Lack of expandability in the future Let's get the elephant out of the room, Apple puts slower 5400 rpm drives in their iMacs. If you have the option to get it with an SSD it's worth the investment. Though it may take a bit to load programs like Photoshop, once it does it runs very well and quite smoothly. You can upgrade this later down the line to an SSD, but you must detach the front glass and screen to do so, so find a place that has professionals to do so for you. Reality is though, I knew what I was getting into with the drive, and it just means it may take a few moments to launch Photoshop or Premier Pro. Once it's loaded it doesn't need the drive anymore and I have to say I have been very pleased. I've edited a couple videos on it with effects and transitions that didn't give me any issues, and I edit from attached storage which also helped with the slow drive issues I would have had otherwise. The screen is phenomenal, and the extra resolution is a godsend when editing videos or working on high resolution files. It simply is a great device and I couldn't recommend it enough. ... show more

    • Worth what I paid for it
Set: Intel Core i5 | 8 GB RAM | 1 TB HDD
I wasn't sure what I was getting buying a refurbished Mac. So far it's been fine. Takes a little while longer to boot up than I expected, but I can overlook that considering I got a "new to me" Mac for $500. Wish it had Microsoft Office for Mac...have to use my MacBook Pro for that. No big deal. They sent a standard wired keyboard and mouse with it which was nice of them to do, but I went ahead and order the wireless Apple keyboard and already had the Apple wireless mouse. The 21" screen is really big, glad I didn't go for the larger screen, it wasn't needed. Only reason I rated Tech Support so low as you don't get Tech Support with a used Mac, obviously. I have, however, found Apple Tech Support to be very helpful when I have called them for other computers I've had. The webcam works well for meetings on Zoom and the sound isn't half bad when listening to music or podcasts. Overall this was a great purchase and I'm happy with it. ... show more

    • Incredible Value For Cost - Like Having a Brand New Computer
Set: Intel Core i5 | 8 GB RAM | 1 TB HDD
Great choice of purchase. Computer came very well packaged. Like new - I don't think this computer has ever been actually used, other than to turn it on to make sure it works, I suppose. This model of computer is just within the model timeframe to be able to download iOS12 Monterey (which is REALLY nice). The computer has incredibly vivid and sharp colors; 4K+ graphics and a number of different visual software options. The Dolby Atmos and general spatial sound sounds phenomenal, particularly with my Apple AirPod Pros. Some apps even support head tracking. The speed and power of the computer is unbeatable for this price range. Indeed there is 1TB of memory, Quad-core Intel i5 processing at 3.1 GHz. There was a very minor cosmetic scratch, but I will never see it, nor will anyone else. It makes no difference, ultimately. My only main complaint is that it is advertised that an Apple mouse and Apple keyboard are in included. I received a super cheap keyboard and mouse, that are intended for a Windows computer, and are super super cheap at that. I am messaging Woot to see if this can be replaced, as I really expected more from them, as a reputable company. If they respond and satisfy this customer, I'll gladly indicate so! Ultimately, it is almost unbelievable that this deal is even available - It really is a steal for the value. Also, Woot is a trusted and consistent vendor. I was very comfortable placing the purchase with them. If you have the option, I highly recommend this computer, and specifically to use Woot as the vendor (in my personal opinion). Thank you Apple for making such wonderful products, and thanks to Woot for assisting in this transaction. 5/5 stars! ... show more
